Structure for Tamper-Resistance Container

ABSTRACT

A tamper-resistance container structure is disclosed, where the top edge of main body has a ring of lip and the cover piece has a ring of groove to mesh in with the lip when closing the cover to the body; a fold-closing piece has a plurality of ridge-tabs that can be wedged into corresponding notches on the cover piece, locking the closure of the container, allowing sticker strip or product labels to be applied over the junction of the fold-closing piece over the cover piece, creating a tamper-resistance mechanism that is desirable for merchants and consumers.

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates generally to an improved design and construction for containers or boxes where a high level of tamper-resistance can be achieved by a simple mechanism, so that there is an easy way of finding out whether any tampering has been attempted against the content of goods (food items, for example) stored inside the container made pursuant to the teachings of present invention.

Especially in the case of perishable grocery items such as fish, meat, vegetable, fruit and similar produce, having simple and cost-effective tamper-proof mechanism has become ever more important in the market today.

Tamper-resistance, sometimes referred to as tamper-proof, packaging mechanism usually involves an external sealing material that both serve to seal off the covered place and serve as product information and labeling, without any structural design or improvement made to the box/container itself. Because there is no other structural improvement made to the body of the container, such prevention of tampering on the level of the external seal is oftentimes not too effective.

In terms of general product packing, present invention provides a great way of product packaging assembly container where workers do not need to spend substantial amount of time to complete a task of putting products into a container box, due to the simple design of fold-back piece with matching ridge-tabs wedging into the corresponding notches. This creates cost-saving in the human labor and thus is beneficial to many businesses in this regards.

In the case where the container made pursuant to the teachings of present invention is of transparent material, consumers can easily see and be assured of the initial quality of the goods inside and thus reduce the operating hassle of consumers needing to return merchandise due to spoiled food, tampered items, or other unsafe conditions that are often associated with retail business product items without such simple mechanism of locking and tamper-proofing structure.

OBJECTS AND SUMMARY OF THE INVENTION

Present invention provides a simple closure mechanism where a high level of air-tightness can be achieved by a meshing structure of a ring of lip with a corresponding ring of groove, so that the freshness of the food items get to be preserved.

Another object of present invention seeks to provide a simple locking closure of cover to the main body, where a fold-back piece is overlapping the top cover, with some ridge-tabs (on the fold-back piece) wedging into corresponding notches (on the cover), so the closure of a container is made relatively secure.

Yet another objective of present invention is to allow a sticker, either in the form of a strip or a whole-piece product label, to seal off the junction place where the fold-back piece is covering the top of the cover piece, so that if some unwarranted tampering happens, the seal or product label would be broken off and is thus made conspicuous to consumers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In FIGS. 1 and 2, images of an opened and closed container of present invention are shown, where a main body 1 forms an inner space 11 for receiving objects into the container.

A ring of lip 12 exists around the top edge of main body 1. Said ring of lip 12 may not necessarily be in a round ring shape, but generally following the circumference of the top open edge of said main body 1.

A first fold-connector piece 21 is formed to connect main body 1 and a cover piece 2. A ring of groove 22 is formed around the periphery of cover piece 2 so that when said cover piece 2 is folded to close the main body 1, as shown in FIGS. 1 & 2, said groove 22 is tightly meshed with the ring of lip 12. The lip 12 and the groove 22 are made to match their relative sizes, so that when cover piece 2 is pressed towards the main body 1, a securely closed container is made.

A fold-closing piece 3 is formed on one side of main body 1 at the end farthest from the fold-connector piece 21. A second fold-connector piece 31 serves to link said fold-closing piece 3 to main body 1, so that when the container is closed (where the groove 22 is tightly meshed in with the lip 12 when the cover piece 2 is folded to close off the main body 1), said fold-closing piece 3 can be folded back on top of cover piece 2, as shown from FIG. 2 to FIG. 3.

A plurality of ridge-tabs 33 are formed on the side that is to be in contact with the top surface of cover piece 2. A plurality of notches 23 are formed on one end of cover piece 2 where said ridge-tabs 33 can be pushed into and wedged against said notches 23, locking the closure of the container.

A sealing strip 4 can be made to come with the container/box, attaching and extending from the outmost edge of the fold-closing piece 3, so that when the container is in a closed stated, as shown in FIG. 3, said sealing strip 4 can be used to seal over the junction place, as shown in FIG. 4, where the fold-closing piece 3 is folded over the cover piece 2.

Said sealing strip 4 can be made to be a separate product supply item, or it can be made to come with the container, having already half sticking to the fold-closing piece 3, ready for use when the container is closed and the fold-closing piece 3 is folded over to create the locking closure.

As such, this combination of the desired features creates a simple and effective tamper-proof container. If any tampering is attempted, the seal and the locking closure structure disclosed herein will easily present proof of tampering.

Alternatively, a product label 5 can be made to come with the product, as shown in FIG. 5, so that the use of the product label not only serves a “sealing” function for the desired tamper-proof purpose, pricing, date and other nutritional fact information can also be imprinted on said product label, as well as other decorative features that may be obtained. 

1. A structure for tamper-resistance container, comprising: a. A main body with an inner space and a cover piece connected to said main body by a first fold-connector piece; b. A fold-closing piece connected to said main body by a second fold-connector piece; and, c. A plurality of ridge-tabs on one side of said fold-closing piece and corresponding number of notches on one side of said cover piece, where the sizes for ridge-tabs and notches are so made that ridge-tabs can be wedged into said notches when the cover piece is in closed position in contact with the top edge of said main body and the fold-closing piece is folded over the outside top surface of said cover piece, creating a locking closure.
 2. The structure of claim 1, further comprising a ring of lip formed along the circumference of the top edge of said main body, and a ring of groove formed around the periphery of said cover piece, so that when said cover piece is folded to close the top of said main body, said ring of lip and said ring of groove are rightly meshed in together.
 3. The structure of claim 2, further comprising a sealing strip to seal over the junction place where fold-closing piece is folded over the cover piece outside top surface.
 4. The structure of claim 2, further comprising a product label to completely tape over the whole top surface area of the cover piece along with the surface portion of said fold-closing piece.
